Muslims are exponentially buying up Christian churches and converting them into mosques, which indicates Islam could be a dominant U.S. religion by the 22nd century.

The former Catholic Church of St. John in St. Paul, Minn., which operated from 1886 to 2013, is now known as the Darul-Uloom Islamic Center and experiences heavy attendance every week.

Similarly, the former Holy Trinity Catholic Church in Syracuse, N.Y., has been transformed into Masjid Isa Ibn Maryam.

“Even as the crosses were cut from the church spires on the outside, and 10,000 crosses were painted over on the inside, the new owners of 501 Park St. tried to leave what they could, and reuse what they couldn’t,” Marnie Elsenstadt with Syracuse.com reported. “The wood from the pews has been repurposed to fix the floor, which is where Muslims sit to pray.”

“Painters worked to make the minbar, the pulpit where the imam stands, blend in with the stonework.”

And two Baptist churches in Louisville, Ky., have been turned into mosques.

The demand for mosques is being driven primarily by refugees from Syria, Somalia and other countries where Islam is a dominant religion.

And it’s not just the demand driving this religious transformation; Christian churches are going bankrupt as Americans become increasingly secular, meaning it’s a buyer’s market for newly-arrived Muslims looking for church property to call home.

“We are on the brink of a massive transfer of kingdom assets,” Pastor Todd Robertson of the Antioch Baptist Church said. “I’m talking about property — buildings and things like that — of churches that, in their heyday of the ’50s and ’60s, were exploding with growth.”

Attendance at the aforementioned Church of St. John, for example, declined from 1,400 to only 400 over the past several years.

Overall, Americans who identified themselves as Christians dropped eight percent since 2007, according to the Pew Research Center.

And, interestingly, President Obama signed an executive order on Nov. 21, 2014, directing all federal agencies to create “Welcoming Communities and Fully Integrated Immigrants and Refugees.”

This executive order coincided with a list of 190 U.S. “host cities” containing federal “refugee processing centers,” including Amarillo, Texas, Casper, Wyo. and Mobile, Ala.
